Re observed on amd64, Google has 5 hits (I assume this bug report will shortly
appear too) for `"vm_reserv_depopulate" "is clear"`, all but one of which are
just for the code, with the final one being for this 5 year old GitHub Gist
https://gist.github.com/nomadlogic/ba58e8fd01267fbf7a2fa4fcee29e2f7 that was
for FreeBSD 12.0-CURRENT on amd64 when using the old freebsd-base-graphics
tree.
Looking at vm_reserv itself, whilst a caller can do stupid things and
potentially cause crashes, my initial reading is that this KASSERT should be
impossible no matter what the caller is doing.
